One day two Astartes were walking down the street

By Baron Throatpunch, in Deathwatch

and one of them was an Assault Marine.

"My Space Wolf has no nose!"

"How does he smell?"

"Terrible!"

I was walking through the park the other day, and I saw a Tech-Priest playing regicide with a servo-skull.

"Wow!" I said, "That's gotta be the smartest servo-skull I've ever seen!"

"Not really," said the Tech-Priest, "I beat him every time."

It might be sleep deprivation addling my mind, but I don't understand the first joke.

Let us together discover if I can make a linky-thingy!
